Good idea, is there a way that when some rotten seller get's themselves a new ebay id to rip people off again, you can tell that the info is coming from the same computer and not let them sell anymore? Got ripped off for speakers to the tune of $550 from a reputable guitar player. Paypal says they will give money back IF it's in seller's account (which I'm sure has been changed by now). Any way to mark someone so they can't just change their name and do it again?
